| 摘要 | A motor includes a stator core, a rotor core that is disposed on an inner side of the stator core and has a plurality of magnet holes arrayed in a circumferential direction, and a plurality of permanent magnets respectively disposed in the magnet holes. The stator core is constructed by a plurality of plates formed from a first magnetic material, each of which has a first thickness. The rotor core is constructed by a plurality of plates formed from a second magnetic material, each of which has a second thickness. The first thickness is smaller than the second thickness, and a silicon content rate of the first soft magnetic material is larger than a silicon content rate of the second soft magnetic material. | ||||||
